How to detect side mouse clicks?

how to detect side mouse clicks? I'm making a console macro in python with keybindings, I need it to detect pressing the side buttons of the mouse. Here is the code:

import keyboard as kb
import mouse
from time import sleep

i = 0
k = 0

st_key = input('Клавиша старт L: ')  
s_key = input('Клавиша старт R: ')
stop_key = input('Клавиша стоп: ')

def func():
    global i
    while i < 5:
            i += 1
            sleep(0.02)
            mouse.double_click(button = 'left')
    b = True
    i = 0

def fun():
    global k
    while k < 5:            
            k += 1
            sleep(0.02)
            mouse.double_click(button = 'right')
    l = True
    
    k = 0

def n():
    global b, i
    while True:
        if kb.is_pressed(st_key):
            func()

        if kb.is_pressed(s_key):
            fun()

        try:
            if b == True:
                i == 0
                b = False
        except:
            pass 

        try:
            if l == True:
                k == 0
                l = False
        except:
            pass 

        if kb.is_pressed(stop_key):
            break
n()

The side mouse buttons are also macros on the mouse itself. They either emulate keystrokes on the keyboard, or a separate action (double/triple click, etc.).
To determine that the button on the device was simply pressed, you need to smoke the mouse driver and work with it.
